Carbon dioxide-enhanced virtual MDCT cholangiopancreatography

Carbon Accounting for Carbon Dioxide Enhanced Oil Recovery

Carbon dioxide insufflation for more comfortable endoscopic retrograde cholangiopancreatography: a randomized, controlled, double-blind trial.

BACKGROUND AND STUDY AIMS The effect on abdominal pain of using carbon dioxide (CO2) for insufflation during endoscopic retrograde cholangiopancreatography (ERCP) has not been investigated. The present study aimed to compare CO2 insufflation with standard air insufflation with respect to the pain experienced during and after ERCP. In addition, we investigated the effect of CO2 insufflation on t...

Spatially confined catalysis-enhanced high-temperature carbon dioxide electrolysis.

In this study, a potential ilmenite cathode material Ni0.9TiO3 is designed for efficient CO2 electrolysis in an oxide-ion-conducting solid-oxide electrolyzer. Spatially confined catalysis has been successfully achieved to substantially improve cathode activity by in situ growth of catalytically active nickel nanoparticles on a ceramic skeleton. The combined analysis of XRD, SEM, EDS, XPS, TGA a...

Microwave enhanced polarization in a carbon dioxide molecule.

This paper presents the results of the dielectric response of carbon dioxide measured using a loaded microwave cavity operating in the TE011, mode of a cylindrical cavity near the frequencies 8.8, 9.7 and 10.2 GHz. The temperature dependence of the dielectric response of gas phase CO2 over the range of 160 to 213 degrees K (-113 to -60 degrees C) was measured. Slater perturbation equations for ...

Aversiveness of carbon dioxide.

Carbon dioxide can produce aversive stimulation of the upper airways, and in their recent review Conlee et al. (2005) emphasized: ‘y Leach et al. (2002) concluded that CO2, either alone or in combination with argon, cannot be used humanely at any concentration and is therefore unacceptable as a euthanasia agent for laboratory rodents, particularly when more humane methods exist. The findings of...
